Goal 2

Algebra - The learner will use relations and functions to solve problems.

Objective 2.03

Create, interpret, and analyze best-fit models of linear, exponential, and quadratic functions to solve problems.

  • Interpret the constants, coefficients, and bases in the context of the data.
  • Check the model for goodness-of-fit and use the model, where appropriate, to draw conclusions or make predictions.
